a railway car truck wherein the side frame is provided.- with aspherical surface seated upon a complementary spherical surface atop thejournal box, the side frame and journal box being aflorded novel meansfor limiting relative angularity between the box and the frame.

Another object-of my invention is to provide in ajournal box mountingsuch as above described, a novel tiebar or securing bracket underlyingthe box and secured to the frame, said bracket havin a spherical surfaceslightly spaced from an adjacent spherical surface of the journal box toaccommodate the above-mentioned angularity between the box and theframe. The bracket and the box are also provided with complemen-- taryabutment faces for limiting vertical angling.

In the drawings,

Figure 1 is a sectional view through a side frame and journal boxembodying my invention, said view being taken approximately in thetransverse vertical plane indicated by the line l-l of Figure 2.

Figure'2 is a fragmentary side elevation of my novel side frameconstruction with the journal box removed from its associated opening.

Figure 3 is a plan view of the side frame securing bracket shown inFigure 2 and illustrating the connection of said bracket to the sideframe.

Figure 4 is a sectional view taken in the horizontal plane indicated bythe line 4-4 of Figure 1.

Figures 5 and 6 illustrate a modification .of my invention, Figure 5being a fragmentary sectional view comparable to Figure 1 and taken inthe vertical plane indicated by the line 5-5 of Figure Figure 6 is afragmentary side elevation of the side frame shown in Figure 5 with thejournal box removed therefrom. I I Describing my invention in detailand-referring first to the embodiment thereof illustrated in Figures 1to 4 inclusive, the side frame comprised the diagona1 tension andcompression members 2 and 4 defining the window opening 8 and merging attheir ends in a box section above the pedestal or Journalbox opening illdefined by the side frame and the removable bracket or tie bar 5 Theside frame above the opening l0, as best seen in Figure 1, is of boxsection comprising the top and bottomwebs l4 and i6 and the inboard andoutboard walls l8 and 20, the top wall l4 being cored away at 22 (Figure2)' to afford an opening for the application and removal of the nut 24threaded on the securing bolt 26 which extends through aligned bosses 28and 30 formed respectively on the bracket l2 and on the side framebetween the inboard and outboard walls l8 and 20. A nut 32 is alsothreaded on the lower end of thebolt 26. The bracket I2 is also securedto the side frame by another bolt 34 which extends through alignedbosses 36and 38 formed respectively on the bracket 12 and side 'framegusset 40. Nuts" and 44 are threaded on opposite ends of the bolt 34.

The bottom wall I6 is formed'on the bot-tom thereof with a sphericalsurface 46 struckon radius A (Figure 1) from the center of curveture B,said'surface 46 being defined by the outboard and inboard convergingabutment sur-. faces 48 and 50 adapted for abutment respectively withthe outboard and inboard surfaces 52 and 54 of the Journal box generallydesignat- 80 ed 56, said surfaces 52 and 54 defining the outboard -andinboard edges of a spherical surface 51 on the top of the journal boxcomplementary to the before-mentioned spherical surface 46 and affordinga seat therefor. It may be noted that the surface 48 and the adjacentsurface 52 are disposed in planes 0 and D converging at a point on acircle E, struck from the point B. By means of this construction, theplanes C and D are both'intcrsecting at a common point on a radius ofthe circle E, thus -insuring flat face contact between the surfaces 48and 52 to'limit relative vertical angling of the side frame and journalbox, as will be clearly apparent to those skilled in the art. Itwillalso be understood that the surfaces 50 and 54 are similarlydisposed in converging. planes intersecting at a common point on thecircle E.

Itmay be noted at this point that the tiebar w I 2 comprises a sphericalsurface 58 struck from the radius F, said surface being concentric withand slightly spaced from a complementary spherical surface 60 formed onthe bottom of the journal box 56, thus accommodating "theabove-mentioned angling between the side frame and thebox.

- ll The surface 60 is defined at its inboard and outboard margins bythe diagonal converging faces 62 and 64 formed and arrangedforcooperation with inboard and outboard diagonal converging faces 66 and68'formed on the tie bar l2, and it will be understood that the surface62- and the adjacent face 66 are formed respectively in convergingplanes 6- and H intersecting at a common point on the circle E, thusaffording fiat face contact therebetween simultaneously with the contactbetween the surfaces 48 and in planes intersecting at a common point onthe circle E, whereby they are afforded fiat face engagementtherebetween simultaneously with the engagement between thesurfaces 60and 54 to limit vertical angling between the box and theframe intheother direction,

The outboard wall 20 is formed with a hollow lug 18 received within abracket I2, U-shaped in horizontal cross-section with the parallel wallsof said -brackethaving the inner surfaces thereof converging toward'thelug 10, as seen in Figure 4, and it will be understood that the parallelsurfaces on the lug 10 have fiat face engagement .embodiment, by rollerbearing units Y 52 to limit vertical angling between the box and theframe in one direction. Similarly, the sur-- face 64 and the adjacentface 68 are disposed.

arcuately formed to accommodate limited Vera.

tical angling of thesid'e framelongitudinally thereof, and said openingis somewhat triangular in vertical cross-section, as best seen in Figure3 5, to accommodate relative vertical angling between the wheel and axleassembly ..228.'and the side frame transversely thereof, as best seen'in Figure '5. a

It will be understood that the arrangement 11 lustrated in Figures 5 and6 is substantially identical to the previously described embodiment,

except for the elimination of the tie bar and for the particular.connection between the side frame and journal box afforded .by the bolt2361:

i and the lug 232, as above described; and it may with the convergingsurfaces of the bracket 12 to limit horizontal angling between the sideframe I and journal box in opposite directions. The axle [4 of the wheeland axle assembly fragmentarily indicated at I6 is received within thejournal box 68 and is mounted therewithin by means of inboard andoutboard roller bearing units, the inboard bearing unit consisting of anouter race 18 fitted within the box against a shoulder 80 therein, andan inner race 82 carried by the axle 14. Roller bearings 84, 84' aredisposed between the races 18 and 82. The outboard roller bearing unitcomprises an outer race 86 fitted within the Journal box against ashoulder 88 therein and an inner race 88 sleeved on the axle l4, rollerbearings 82,

for positioning the races Hand 82 and the sleeve 84.

' A cover plate 98 is secured as at I88, I88 to the outboard face of thejournal box, and an inboard cover plate 1021s secured as at I04, I84 tothe inboard side of the box, said plate I82 being grooved at 186, I06and defining with the shrink collar I08 9.: labyrinthine passage M0 toprevent the escape of oil from within the journal box.

be noted that because of the'elimination of the tie bar, the side frameis provided beneath the spherical surface 2I8 with the spaced dependingpedestal lugs or jaws 242, 242 adapted tov ern- 'brace the journal boxtherebetween to prevent accidental disassembly thereof with respect tothe side frame.

It is to be understood that I do not wish to be limited by the exactembodiments of the device shown which are merely by way of illustrationand not limitation asvarious and'other forms of the device will, ofcourse, be apparent to those skilled' in the art without departing fromthe spirit of the-invention or the scope of the claims.
